Title: Control method of variable stator blade of gas turbine fan and compressor
Inventor: FURUKAWA HIROYUKI
IPC: F04D27/00
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To effect appropriate value setting of the opening of a variable stator blade even during acceleration, by obtaining a corrected variable stator blade in accordance with the angle of inclination of the variable stator blade with respect to the acceleration rate and correction speed of an engine during acceleration, and calculating this corrected variable stator blade angle. SOLUTION: A corrected speed NGC 25 with respect to actual measured air temperature is obtained from the air temperature TT 25 at the compressor inlet and gas generator speed NG. Next, the setting angle VSV- SS of the variable stator blade to which it should be set is obtained. Also, the acceleration rate δ NGC 25 of the engine is obtained by the control timing of a control device 10. The change width (inclination) δ VSV- SS/δ NGC 25 of the setting angle of the variable stator blade with respect to the corrected speed NGC 25 is obtained. The inclination δ VSV- SS/δNGC 25 of the variable stator blade based on the corrected speed NGC 25 is obtained from this relationship.  In this way, the corrected amount of VSV- TR of the variable stator blade obtained with respect to the corrected speed NGC 25 is output as the set angle VSV- REF of the variable stator blade during acceleration.

Title: Magnetic recording medium
Inventor: MINAMI KATSUTOSHI
IPC: G11B5/73
Filed: 1988-03-31
Abstract: PURPOSE:To improve the adhesiveness of a synthetic resin substrate and Cr layer by interposing an oxide layer of Si between the synthetic resin substrate and the Cr layer. CONSTITUTION:This magnetic recording medium is formed by forming the Cr layer 3 and a thin magnetic material film 2 successively on the substrate 5 consisting of the synthetic resin. The layer 4 consisting of the oxide layer of the Si is formed between the substrate 5 and layer 3 of such magnetic recording medium. The adhesiveness of the substrate 5 and the layer 3 is thereby improved and the uniform Cr layer which does not exfoliate from the substrate 5 and does not crack during use is formed. The thickness of the layer 4 is preferably >=500Angstrom . The sufficient prevention of the crack of the Cr layer is not possible in some cases if the thickness thereof is below 500Angstrom . The oxide of the silicon has preferably >=0.6 range of x when said oxide is expressed by the general formula: SiOx. The adhesiveness to the substrate 5 and the layer 3 is insufficient and, therefore, the sufficient prevention of the crack of the layer 3 is not possible in some cases if the range of x is below 0.6.

Title: Heterojunction bipolar transistor
Inventor: JIYON KEBIN TOWAINAMU
IPC: H01L21/331
Filed: 1993-04-07
Abstract: PURPOSE:To reduce the density of carriers in an emitter-base junction region, to make low a surface recombination current and to prevent a reduction in the reliability of the transistor, caused by a surface regenerative combination, by a method wherein a transition layer is changed from the side of a base layer to the side of an emitter layer with a linear or step-by-step inclination of compositions. CONSTITUTION:As a potential well is not formed in the conduction band of an emitter layer 6 and electrons are implanted in a base layer 4 at high speed, the density of electrons in an emitter-base junction region is reduced and the density of holes in the emitter-base junction region is maintained in a state that the density is low. This is because an ON voltage of the emitter-base junction part is low by a comparatively small stage due to the compositional ratio of a transition layer 5 between the transition layer 5 on the side of the layer 4 and the layer 4. Accordingly, as the density of carriers, in short, the electrons an the holes, in the emitter-base junction region is low, an SHR recombination current can be maintained at a low level.

Title: Information recording and reproducing method
Inventor: AIDA SEIICHI
IPC: G11B20/00
Filed: 1983-05-11
Abstract: PURPOSE:To decrease the strokes produced from adjacent tracks by recording repetitively the still picture video signals equivalent to a frame to the continuous tracks equivalent to three rounds and scanning repetitively the center still picture video track with a video head. CONSTITUTION:When the still picture video signal is recorded to a video disk, the same still picture video signal is recorded to at least 3 still picture video tracks 12A-12C respectively. Then the center still picture video track is scanned repetitively with a video head 12B so as to avoid the deterioration of the still picture quality owing to the strokes of adjacent tracks 12A and 12C. Thus the quality is never deteriorated for reproduced still pictures although the strokes are produced from adjacent tracks during the repetitive scan since the same still picture video signal as that of the track receiving the repetitive scan is recorded to the adjacent tracks.

Title: Protection circuit for removable controller
Inventor: KATO KIYOSHI
IPC: G11B33/12
Filed: 1990-03-30
Abstract: PURPOSE:To prevent destruction of an internal circuit such as an IC circuit, to reduce the cost and to make the device small by connecting a protection diode between a ground terminal and a power input terminal of an operating power supply with a lower voltage in the two power supplies in the reverse polarity. CONSTITUTION:A protection diode 9 is connected between a ground terminal 7b and a power input terminal 7a of an operating power supply with a lower voltage in the two power supplies VDD, ILL in the reverse polarity. When a contact timing of a ground contact 7b is delayed more than that of other two power contacts 7a, 7c at the removal of an operation section 3, a protection diode 9 is conductive by a reverse voltage caused between a voltage difference of the two operating power supplies VDD, ILL. Thus, a reverse voltage caused between the ground GND and the power input terminal 7a at a lower voltage level reaches only a voltage equivalent to a forward voltage drop of the conducted protection diode 9, and an internal circuit such as an IC circuit connecting to the operating power supply VDD at a lower voltage is not destroyed due to the reverse voltage. Thus, the destruction of the internal circuit such as an IC circuit is prevented, the cost is reduced and the device is made small.

Title: Two-dimensional ccd image sensor and its driving method
Inventor: ODA HIDETSUGU
IPC: H04N5/335
Filed: 1986-04-09
Abstract: PURPOSE:To improve the vertical resolution by generating a vertical shift pulse from a shift register connected to each transfer electrode constituting a vertical CCD register so as to pickup an image by an interlace system. CONSTITUTION:Signal charges from photodiodes 31-45. are read in a corresponding 1/2-stage vertical CCD register 81 (comprising 46-48) in the vertical blanking period. When the shift pulse fed to the elecrode C of the closest vertical register to the horizontal register 82 is turned off in the horizontal blanking period, the signal charge under the electrode is transferred to the horizontal register 82. Then shift pulses from shift registers 51, 52 are fed to the transfer electrode of a vertical CCD register, then the signal charge is sequentially transferred to the horizontal register without being mixed in the vertical CCD register and outputted. Since the on/off stage of the shift pulse is changed only in the blanking period, no disturbance is given to the video image at the effective period.
